    • A compact Thévenin model for a rectenna and its application to an RF harvester with MPPT 

      Gasulla Forner, Manuel; Ripoll Vercellone, Edgar; Reverter Cubarsí, Ferran (Multidisciplinary Digital Publishing Institute (MDPI), 2019-04-06)
      Article
      Accés obert
      This paper proposes a compact Thévenin model for a rectenna. This model is then applied to design a high-efficiency radio frequency harvester with a maximum power point tracker (MPPT). The rectenna under study consists of ...

    • A High-Efficiency RF Harvester with Maximum Power Point Tracking 

      Gasulla Forner, Manuel; Robert Sanxis, Francesc Josep; Jordana Barnils, José; Ripoll Vercellone, Edgar; Berenguer Sau, Jordi; Reverter Cubarsí, Ferran (Multidisciplinary Digital Publishing Institute (MDPI), 2018)

      Accés obert
      This paper presents the implementation of a high-efficiency radiofrequency (RF) harvester, which consists of a rectenna and a maximum power point tracker (MPPT). The rectenna was characterized from -30 dBm to -10 dBm at ...

    • An Add-On Electronic Device to Upgrade Mechanical Gas Meters into Electronic Ones 

      Ripoll Vercellone, Edgar; Ferrandiz, Vicent; Gasulla Forner, Manuel (Multidisciplinary Digital Publishing Institute (MDPI), 2018)
      Text en actes de congrés
      Accés obert
      Smart utilities enable more efficient energy consumption and distribution and are the key for smart homes development. We propose an electronic device that will be integrated as an add-on to already installed conventional ...

    • Design and implementation of wireless nodes for the Internet of Things 

      Ripoll Vercellone, Edgar (Universitat Politècnica de Catalunya, 2022-04-01)
      Tesi
      Accés obert
      The Internet of Things is a trending topic these days. However, energy is often the major job stopper for broad adoption of this technology, which have three tight constraints: extremely cost oriented, long service life ...

    • Electronic reading of a mechanical gas meter based on dual magnetic sensing 

      Ripoll Vercellone, Edgar; Gasulla Forner, Manuel; Reverter Cubarsí, Ferran (2021-06-08)
      Article
      Accés obert
      This article proposes a measurement system controlled by a microcontroller unit (MCU) for the electronic reading of a mechanical gas meter. The measurement relies on dual magnetic sensing: (a) low-cost low-power primary ...

    • Experimental characterization of off-the-shelf LEDs as photodetectors for waking up microcontrollers 

      Ripoll Vercellone, Edgar; Reverter Cubarsí, Ferran; Ferrandiz, Vicent; Gasulla Forner, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The use of LEDs as photodetectors has been subject of study for a long time. However, LEDs manufacturers do not provide information about the response of LEDs to the light. It is essential for the designers of electronic ...

    • LED-Based Wake-Up circuit for microcontrollers 

      Ripoll Vercellone, Edgar; Reverter Cubarsí, Ferran; Gasulla Forner, Manuel (2020-07-15)
      Article
      Accés obert
      This article proposes, analyzes, and tests a wake-up circuit for a microcontroller (MCU) that uses a light-emitting diode (LED), operating as a photodetector, illuminated by a smartphone flashlight. The wake-up circuit ...

    • Using LEDs for Visible Light Communication and as a Wake-up Mechanism in the Internet of Things
